Various effective altruists have suggested that avoiding farmed fish is one of the most important things you can do to reduce the amount of suffering caused by your diet. Fortunately, an almost perfect substitute for farmed fish exists: wild-caught fish. It is very unclear whether eating more wild-caught fish is good or bad for fish. Replacing a food that’s very bad with a food that might be good or might be bad seems like progress.
However, it does not seem like there are any guides for how best to replace one’s farmed fish consumption with wild-caught fish.
I am offering a bounty of up to $500 for a well-written, easy-to-understand guide to replacing farmed fish with wild-caught fish. Questions that might be addressed by this guide include:
Which, if any, species of fish are always farmed?
Which, if any, species of fish are always wild-caught?
How likely are farmed fish to be mislabeled as wild-caught? Are there heuristics to use to avoid mislabeled fish?
If you don’t know whether a fish is wild-caught or farmed, how do you figure it out?
How likely is a fish of unknown origin to be wild-caught? Farmed? What factors affect whether it is wild-caught or farmed?
What are the cheapest ways to buy wild-caught fish?
What are the best wild-caught substitutes for commonly eaten farmed fish?
Which fish oil pills, if any, use wild-caught fish?
The full $500 will be paid out for a complete, well-researched, well-copyedited, easy-to-understand guide that is ready to be given to interested reducetarians. Incomplete or poorly edited reports will receive a portion of the bounty depending on my judgment of their quality. Reports with factual errors or which are otherwise very low-quality will not receive any money.
People interested in the bounty are encouraged to email me at firstname.lastname@example.org so I can connect them to other interested people, for coordination and to avoid duplication of work.
